Abstract

A liquid crystal display device in which an integrated printed circuit board is manufactured by integrating a circuit of a gate portion with a source portion and is located on the source side of the liquid crystal panel, and a flexible circuit board according to the COF method is provided on the gate side, and the flexible circuit board is supported towards a mold frame to reduce the area and the volume which is occupied by a portion except for a screen is disclosed. The liquid crystal display device comprises a liquid crystal display panel, an integrated printed circuit board, a flexible circuit board for transferring a gate driving signal and a data driving signal to the liquid crystal display panel, and a mold frame for receiving the liquid crystal display panel and a back light assembly. A support member for supporting the flexible circuit board towards the mold frame is provided on one side of a chassis. Since the gate side flexible circuit board is easily supported by the support member towards the mold frame, the planar area increasing of the liquid crystal display device is prevented.
